Application filed. March 20, 19-12. Serial No. 685,000.

To all whom it may concern:

Be it known that I, SILVIO COGANARI, technologist, a subject of the King of the Belgians, and resident of 152 Chausse dAnvers, Vieux-Dieu, Belgium, have invented a certain new and useful Magazine Film- Holder, of which the following is a specification.

The present invention relates to an external case with a lateral rectangular aperture (the lower edge of the rectangle being cut so as to have the shape of an open V). In this case are fixed one or more supports carrying the sensitive surfaces. All supports are covered by a second case, movable in the first in such a manner that it is possible at the same time as the interior case is raised to lift one, two or three supports, so as to expose the next sensitive surface, each support being provided with a projection, the number of which appears behind an aperture in the interior case, which aperture is provided of a material non-actinic to light.

Figure 1 shows a perspective view of the exterior case. Fig. 2 shows a perspective view of the interior case. Fig. 3 shows a perspective View of the interior case with the closing strip. Fig. 4'shows a view of one of the supports with a sensitive surface. Figs. 5 and 6 show supports carrying sensitive surfaces. Fig. 7 shows a view of the parallelepiped. Fig. 8 shows the supports and the parallelepiped assembled. Fig. 9 shows a perspective view of the frame. Fig. 10 shows a perspective view ofthe frame half open. Fig. 11 shows a perspective view of the device for exerting pressure intermittently, when at rest (without exerting pressure). Fig. 12 shows a perspective view of the same device for exerting pressure intermittently, when open and exerting pressure.

The case 1) is provided of a material impermeable to light, and is of slightly larger dimensions than those of the sensitive surfaces which it is to contain and is sufliciently large to allow freedom of movement in an upward direction to these surfaces one over the other. One wall of the case (1) is provided with a label (3) on which the operator may write his observations. In the other wall is formed an aperture (2) allowing of the passage of light rays coming from the objective. This aperture corresponds to the sizes usually employed in photography. The lower corners of this aperture (2) are rounded and the lower edge is out, not in a straight line but following two lines converging toward the middle, to a point out side the rectangle. The upper small side of the case (1) is completely open and in its lower small side is provided a slit II- of about l5'by 1 millimeters in size.

The interior case (4) which is provided of .a material impermeable to light, slides vertically in the exterior case (1), but is higher by several centimeters. only completely open at its lower side. In the part which projects beyond the first'case are provided a number of holes (5) equal in number to the sensitive surfaces, or to the number of surfaces less one, contained in the frame. These holes are covered with a transparent substance, the color of which is non-actinic to light. A piece of paper (6) or other black and flexible substance is gluec to the lower extremity of the wall of the case (4), in which holes are not provided. This strip of paper (6) is folded on the case. It has the same width as the rectangular aperture (2) provided in the first case (1), and it passes through the aperture (2). It rests continually on the exterior of the case (1) and serves to limit the motion of the interior case (4) and to prevent the passage of light between the two cases. The upper extremity of this strip, after the frame is fitted together, is glued to the upper and outer extremity of the case (4).

Two or more pieces of black paper 7, 7", 7, (Figs. 4, 5 and 6) or other flexible substance impermeable to light, have their lateral and lower edges cut in straight lines, but the upper edge is provided witha projection (9) of the same substance. This projection (9) has the same height for all the supports, but varies in width. The projection (9) of the first piece 7 is of sufficient width to show itself behind all the holes (5). The second projection 7 covers one less and so on in succession. Behind these surfaces (let us consider as fore-part the surface of the supports which cover the rectangular aperture of the first case) is situated the device for exerting pressure intermittently (8). This device is composed of a parallelepiped (8) Figs. 11 and 12 made of four pieces card board or other rigid material. The angles of the four pieces are glued together with flexible linen in order that the parallele- This case (4) is piped may be deformed. The dimensions of the parallelepiped are: 1. The large planes are of the size of the sensitive surfaces carried by the frame. 2. The small planes have one side of the same size as the sensitive surfaces and the other equal to the interior depth of the second case 4. This parallelepiped, owing to the flexibility of the linen with which the angles are made, may be deformed, that is to say, the two great planes can be brought together always parallel to one another, until one touches the other. This is the usual position of this parallelepiped. One of the two great planes, is provided at its lower part with a small prolongation (10) which passes through the slit (11) of the case (1) and which is 'glued to this same case. The other plane has its upper portion glued to the case by means of a strip (12), so that on rising this case carries it with it at the end of its path. In this manner, the planes are caused to separate from eachother and to press the sensitive surfaces against the aperture of the first case, whereas when the case (4) commences to descend, the pressure completely ceases.

To each piece of black paper (7 and on the exterior surface of the plane of the parallelepiped (8) on the side of the opening, are attached sheets (18), of sensitized thin material. The pieces of paper are placed one upon the other (Fig. 8) in such a manner that the first is that with the largest projection 7' and the last is that with the narrowest projection. On the back of these projections and corresponding with the holes are provided numbers. The sheets of paper carrying the sensitive surfaces are secured to the first plane of the parallelepiped by means of a piece of thread (14), metallic or otherwise, or in any other manner.

The pieces of black paper 7, 7", 7 and the parallelepiped (8) provided with their sensitive surfaces (13) after being connected together, are introduced into the case 4) in such a manner that the numbers marked on the projections show themselves through the transparent non-actinic substance which covers the holes The case thus prepared in the dark room is introduced into the case (1) so that the sensitive surfaces are presented to the rectangular aperture (2), and so that the prolongation (10) of the parallelepiped projects through the small slit (11) formed in the bottom of the case (1). This prolongation is then folded and glued to the case The frame is then ready for use.

On sliding the case (4) in the case (1) and compressing No. 1, the supports held by the thread (14) which connects them to the parallelepiped fixed by the prolongation (10) to. the first case (1), do not rise with the case (4) and consequently the first sensitive surface is exposed. After having made the exposure, the case (4) is lowered. For the second exposure the case 4 is then caused to re-mount compressing the hole carrying No. 2. The projection (9) of the first support 7 is then taken between the thumb and index finger thus compressing the case 4), and rises with it breaking the thread (14) which joins it to the parallelepiped (S). In this manner the second sensitive surface is exposed. After the exposure, case 4 is lowered and the first exposed sensitive surface with its support resumes its former place in front of the second one. For exposing the next sensitive surface, the next window of case is pressed between thumb and finger and case (4) is raised. The pression of thumb and finger on the window of case (4) brings the sides of this case near one another, compressing between them the supports projections of the previously exposed sensitive surfaces. The previously exposed surfaces are thus raised at the same time as case (4) and remain in case during the exposure. After the exposure the previously exposed films are replaced at their initial places, by simply lowering case (4) that contains them. By raising and lowering in the same man ner, and compressing between the thumb and index finger the holes carrying the successive numbers, all the sensitive surfaces will be exposed in turn.

The last sensitive surface will not rise, since it is fixed to the parallelepiped.

Each time the case (4) rises, it carries with it the plane of the parallelepiped (8), which is glued to its extremity by the strip (12). p The parallelepiped opens, and presses the sensitive surfaces against the internal surface of the case (1), provided with the window (2) in such manner that they come together.

When the case (4) is pushed into the interior of the case (1) the frame is C0111 pletely closed to light and can be taken out of the apparatus. It is therefore not necessary to await the exposure of all the sensitive surfaces before developing.

The case (4) in its upper portion is provided with an aperture by which the exposed surfaces with their supports may be removed, while those which have not been exposed remain in the frame ready for use. The frame is placed directly in the apparatus without the use of any adapter whatever.
